+Hash containing enviroment variables including many special variables inserted
+by WWW server - like SERVER_*, REMOTE_*, HTTP_* ...
+
+Before accesing enviroment variables consider whether the same information is
+not directly available via Catalyst objects $c->request, $c->engine ...
+
+BEWARE: If you really need to access some enviroment variable from your Catalyst
+application you should use $c->engine->env->{VARNAME} instead of $ENV{VARNAME},
+as in some enviroments the %ENV hash does not contain what you would expect.
